Guerrilla RF has introduced the new products to its family of 5 GHz ultra low noise amplifier/linear power amplifier drivers. These new devices feature a very low noise figure (NF), high gain and linearity. These cost-effective, small footprint, flat-gain solutions are designed for WLAN access points for demanding 802.11ac applications. The emergence of high performance 802.11ac applications has created the need for a new generation of ultra-low noise figure devices with high gain and outstanding linearity. Guerrilla RF is addressing this growing necessity with high-performance low noise amplifiers that utilize bypass-mode capability - crucial for today’s WLAN access points.
Infonetics Research expects the WLAN equipment market to accelerate in 2015 as spending by service providers and education increases and 802.11ac reaches critical mass.
Guerrilla RF’s Newest 5 GHz Low Noise Amplifier/Power Amplifier Drivers
The GRF2505 features ultra-low noise and high linearity over the 5 to 6 GHz band making it ideal as either an LNA or as a power amplifier (PA) driver for demanding 802.11ac applications. With its high IP3 and compression point this amplifier can meet the strict linearity requirements of a high performance driver between the transceiver output and the input to the final PA. As an LNA, its ultra-low NF of 0.8 dB and high input-referenced linearity contribute to both maximum receiver sensitivity and linearity.
The GRF2541 is another ultra-low noise amplifier with bypass designed for IEEE 802.11 a/n/ac/p applications. It is matched to 50 ohms has a 15 dB flat gain and 1 dB NF across the entire 4.9 to 6 GHz band. It builds on the previously announced GRF2501 by adding bypass-mode functionality. This bypass capability improves the receiver dynamic range for improved data rates in high signal strength environments. Guerrilla Armor™ technology also provides exceptional off-state isolation in the presence of high RF input signal levels in LNA power-down mode.
Both the GRF2505 and GRF2541 feature adjustable bias current and Vdd, which allows for optimal application flexibility and efficiency.
